ET STATES LAWRENCE C. SALZER, OF..A.UB`URN,A'NEW YORK BLoW'roRoHApplication inea August 15, 1930. semi no. 475,500.

in the scope ot the invention as claimed, with-V out departing from thespirit thereof.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and the drawingshereto attached, in which:

Figure 1 is a perspective View illustrative ot a blow torch embodyingthe invention.

Figure 2 is an enlarged detail sectional view, parts being broken. away.Y

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likereference characters.

The numeral 1 designates a burner pipe to which is tted a nozzle 2. rIhepipe 1 may be of any length and size a-nd has a handle 3 more or lesstightly but slidably mounted thereon to prevent burning the hand. Fixedto the pipe 1 at its lower end, as seen in Figure 2, is a tapered collar3. A small metal tube 4 extends through the pipe 1 and nozzle 2 and iscentrally disposed within the nozzle and terminates a short distancefrom the extremity thereof. The device includes a Y-fitting whichcomprises a ball 5 and coupling ends 6, 7 and 8. The coupling ends 7 andS are juxtaposed and are outwardly diverged from the ball 5. Thecoupling end 6 is disposed opposite the coupling ends 7 and 8. A smallmetal tube 9 extends through the ball 5 and coupling ends 6 and 8. Aplug 10 closes the outer end of the element 8 and the tube y9 extendstherethrough. A flexible tube 11 connects the coupling end 7 with anoutlet 12 which is controlled by a suitable valve. A flexible tube 13connectsthe coupling end 8 with an outlet 14 which likewise consists ofa suitable valve. A flexible tube '15fcon'nects the coupling end 6 withthe end of the' burner pipe 1 remote from the knozzle 2,-said tubehaving its kend portion clamped between the flat surface of the collar`3and the dat lower end tace of thevhandle 3. The tube 15 may be otanylength, eight to tenV feet, more or less, ,to admit ot the torchcovering a large area; within the tube 15 and connects the tube 9 withthe tube 4. The tubes 11, 13, 15 and 16 are usually of rubber. The tubes4 and 9 are of' metal.

The branch tubes 11 and 13 are shortv and make provisionv for connectingthe main or extension tube 15 to the air and gas outlets. The outlet 12is connected to asuitable source of gas supply whereas the outlet 14 isconnected with a vsuitable source of compressed air. *When the torch isconnected to the air and gas outlets, the flame may be regulated byadjusting the valves associated with the respective outlets, as will bereadily understood. The gas from the valve controlled outlet 12 passesthrough the branch tube 11, Y-iitting, main tube 15, burner pipe 1, andnozzle 2 and is consumed as it issues from the nozzle. The compressedrair from the outlet 14 passes through the branch tube 13 and tubes-9,16 andv 4, and issues from the tube 4 adjacent the extremity ot thenozzle and discharges into the Haine in a jet, thereby promotingcombustion of the gas and intensit'ying the ilame which may be regulatedto suit the work by adjusting the valves 12 and 14 in a manner readilyunderstood.y It is observed that there is but a single line of tubing 15and a single burner pipe 1, and, in consequence, there is no liabilityof two lines becoming entangled or inconvenience being experienced bythe provision `ot a number of burner pipes.` l

Attention is directed to the fact that the tubing 15 may be removed fromthe pipe 1 inasmuch as the handle 3 may be shifted forwardly for freeingthe end portion of said tubing from between the flat end tace of thehandle and the collar 3. However, under normal conditions, the end ofthe hose will be lirmly held between the handle and said A smallflexible tube 16 yis disposed Y collar so that accidental detachment ofthe hose will be prevented.

What is claimed is:

A blow torch including a burner pipe having anozzle, a collar carried atone end of the burner pipe, a handle mounted on said burner pipe, asmall rigid air tube within the burner pipe and nozzle7 a Y-ittingcomprising a ball and coupling ends, a small rigid tube passing throughthe ball and one of the coupling ends of the Y-itting, a flexible tube vconnecting the burner pipe with the Y-itting and having its end portionnormally clamped between the collar and handle, said handle beingslidable for releasing said end portion 'of the flexible tube wherebysaid flexible tube may be disconnected, asmall iieXible tube within theiirst mentioned flexible tube and connecting the small rigid air tubewith the small rigid tube in the Y-itting, and branch tubes formingconnecting means between the Y-.fitting and valve controlled gas andcompressed air outlets.`
